Laser Slicer (Blender 2.8)

I have updated my Laser Slicer script for Blender 2.8. For those unaware of it, it slices a Blender object up and then exports those slices to SVG file(s). I use it to then cut the 3D form on a laser cutter (hence the name).
A very recent build of Blender 2.8 is recommended.
Code has moved to github and the install-able zip can be got from the master branch:

Bug reports can be filed on the github issues page:

Further details, old versions for 2.7, and a tutorial video can be found at:


Uhm… I’m not able to get the link to work…

Ah. Thanks for letting me know. Links should work now.

lovely add-on. one question: it gives me a group of separate lines (a circle that is separate lines) I know it’s a none blender question but how can you join and smooth them in inkscape?

If you select the ‘SVG polygons’ option you get a SVG polylines and not individual lines as explained in the tutorial video

On inkscape I found that pressing ctrl + shift + c (object to path) will bring the nodes. Thanks awesome add-on!

Hi rareg,

Is Laser Slicer addon can to generate contours map/ line of 3D terrain ?


No Idea why but for some reason I’m getting a trackback error… Is the addon still supported in blender 2.83? Sorry if i’m missing something obvious…

You’re specific error is because you have selected a directory and not a file for export.
I have updated the git repository to get round this and made some other updates for 2.83. Test and post here if problems.

Yes, I think it does what you want.

Hey, awesome plugin!

Just one issue, I’m trying to import the slices in the exact same location into LightBurn, I need to cut multiple layers at the exact same location.
When I import, the outlines of a smaller piece center out instead of keeping their relative position.

Is it possible to choose the height of cutting lines? Now there is the option for thickness, but I would like to shift the cuts in the z axis.

Is is possible to label the individual slices to help in reassembly after laser cutting?
Thanks for developing this. I look forward to seeing what is possible.

Not currently but it is something I may implement in the future.

The addon does not currently consider depth or overlapping slices. Each slice is individual as it is designed for use with a laser cutter.

Fantastic Plugin!
Is there any chance of this being updated for 2.9x?

Is it not working on 2.9? I’ll have a look at it at the weekend.

Thanks for the reply.
I tried, but unlike some other plugins I could not get this working.
Admittedly I am a total newbie, and might have overlooked something, in which case apologies.
I was delighted when I found the plugin, so it would be great if it did work with 2.9.

Hi - did you have any joy with seeing if this was 2.9 compliant. Thanks in advance

I’ve tested it on 2.91. Seems to work fine.

Thanks for the work. Inspired by the addon, I extended it to 2 interlocked slices for plywood/cardboard model with interlocking slots. Hope that this is useful.
